How to prevent Backup of corrupt (0KB) file!!

[michaelharrington]

Somehow a file I use is getting corrupted - and I am left with a 0kb version of the original. Leaving this problem aside. All my backups are then of this corrupt version.

Any idea how to prevent a backup of a 0 kb or corrupt file?

Or a copy command I can schedule to run but only copy if the file is > 10kb

any advice would be greatly appreciated.

This has happened twice now and I have lost the work. I use this file a lot synchronising with 3 systems.
I use a back up program handy Backup

thanks

Michael
